I was stung for the first time in the face yesterday. This hive has been very calm and pleasant and I regularly have been able to work it with no glove, veil, or even smoke. Yesterday was a very different story. This morning I think I have found the reason. I found 4 dead wasps and about 2 dozen dead bees on the landing board and in front of the hive. A real battle must have been raging inside the hive yesterday. Can anyone tell me if this is just something that occurs from time to time, or if it is something I can prevent. Here is a pic of the culprit: https://plus.google.com/photos/10181...67908256811105
What kind of wasp? What can I do about them?
